【中文标题】Spring Boot v2.5.2 - 刷新端点不起作用【英文标题】：Spring Boot v2.5.2 - refresh endpoint is not working 【发布时间】：2021-09-30 13:12:28 【问题描述】：

我正在使用 Spring Boot v2.5.2 微服务并尝试动态刷新端点。我正在使用 Spring Cloud API 网关并实现了安全性，现在当我制作 http://localhost:8012/actuator/busrefresh 时，我看到只有 Spring Cloud API 网关反映了更改，但其他微服务没有。

我们该如何解决？

Spring Cloud API 网关

对于此微服务，刷新总线更改有效，对于用户服务则无效

【问题讨论】：

【参考方案1】：

你的位置是 http://localhost:8012/actuator/busrefresh，这是你的 spring gateway servere location actuator，但是，当你使用 spring cloud gateway 时，你是否使用代理来连接具有统一地址的服务器，也许你可以试试这样“http://localhost:8012/$你的服务器代理位置/actuator/busrefresh”，希望它的工作

以上是关于Spring Boot v2.5.2 - 刷新端点不起作用的主要内容，如果未能解决你的问题，请参考以下文章
